Yun Jiao thought for a moment and said, "Since the worm is in your stomach, it's simple. I'll write a prescription for you that will make you vomit the worm out once you take it."
Marquis Xuanping shook his head, "After I went home that day, I used a toothbrush to poke my throat and vomited for a long time, but I still felt unwell. The worm just wouldn't come out."
Yun Jiao laughed and said, "My medicine has a peculiar effect on worms. You can be sure it will make you vomit it out."
Marquis Xuanping was half-convinced, but then he thought of the news his servants had gathered early that morning: Doctor Gu not only cured the Emperor's toothache but also healed the Princess Consort's eyes.
